An auto lease vs finance calculator reveals the true total cost of each option — not just the monthly payment. Leasing delivers lower payments but no equity; financing costs more monthly but builds ownership. Enter your specific lease terms and loan details below for a side-by-side breakdown including monthly payments, break-even point, equity built, and cost per mile.
Vehicle & Common Details
Applied to both scenarios for apples-to-apples comparison
Lease Details
= 6.0% APR equiv. (multiply × 2400)
Typically 45–65% for 36-month lease
Finance / Loan Details
The comparison period is set to match your loan term. Leasing costs are projected over the same number of months for a fair apples-to-apples comparison.

How to Use the Auto Lease vs Finance Calculator
The monthly payment is the most visible number in any auto deal, but it rarely tells the full story. A lease at $350/month looks cheaper than a loan at $500/month — until you realize the loan ends after 60 months while the lease cycles indefinitely, and the financed car is worth $12,000 when the loan ends. This auto lease vs finance calculator computes the complete picture over the same period: total out-of-pocket, net cost after equity, cost per mile, and the break-even point.
Step 1: Enter Vehicle & Common Details
Start with the vehicle's MSRP (sticker price). Enter your planned down payment or cap cost reduction — the calculator applies this equally to both scenarios for a fair comparison. Add your state's sales tax rate; most states tax each lease payment, while financed purchases are taxed upfront on the purchase price. Finally, enter your expected annual mileage in miles or kilometers.
Step 2: Enter Your Lease Terms
Select the lease term (24, 36, 39, or 48 months). Enter the money factor from your dealer — multiply it by 2,400 to find the equivalent APR. The calculator displays the APR equivalent as you type. Set the residual value as a percentage of MSRP (your dealer provides this; typical 36-month leases run 45–65%). Select the included mileage allowance and the per-mile fee for going over that limit.
Step 3: Enter Your Finance / Loan Terms
Enter the loan's annual percentage rate (APR) your lender is offering and the loan term in months. The comparison period is set to the loan term — leasing costs are projected over the same number of months. For example, if you choose a 60-month loan, the calculator stacks 1.67 lease cycles (60 ÷ 36 months each) to cover the same period.
Understanding the Results
Monthly payments show what you pay each month under each option, including taxes. Total out-of-pocket is all money leaving your pocket over the comparison period (payments + down payment + fees + taxes + any excess mileage charges). Net cost subtracts the estimated vehicle equity at term end from the finance total — since you own a car worth real money at the end of a loan. Cost per mile divides net cost by total miles driven. Break-even point shows when cumulative finance costs dip below cumulative lease costs.
Who Should Lease vs Finance?
Leasing tends to suit drivers who prefer a new vehicle every 2–4 years, drive fewer miles than the lease allowance, use the car for business (lease payments may be deductible), and value predictable maintenance costs during the warranty period. Financing tends to suit high-mileage drivers, people who want to own an asset outright, drivers who keep vehicles 5–10+ years, and anyone who wants to avoid the cycle of perpetual car payments.
Frequently Asked Questions
Is it better to lease or finance a car?
It depends on your priorities. Financing (buying) builds equity and lets you own the car outright after the loan is paid — you can then drive it payment-free or sell it. Leasing offers lower monthly payments and a new vehicle every few years, but you own nothing at the end. This calculator shows the full total cost of each option so you can decide which fits your situation.
How does the money factor affect my lease payment?
The money factor is the lease equivalent of an interest rate — multiply it by 2,400 to convert to an approximate APR. A money factor of 0.0025 equals roughly 6% APR. A lower money factor means lower monthly payments. Dealers can mark up the money factor above the bank's buy rate, so it's worth asking for the base money factor and negotiating it down.
What is residual value in a car lease?
Residual value is the estimated worth of the vehicle at the end of the lease term, expressed as a percentage of MSRP. A 55% residual on a $35,000 car means the leasing company expects it to be worth $19,250 after 36 months. Higher residuals mean lower monthly payments because you finance less depreciation. Residual percentages vary by model, trim, and market conditions.
What is the break-even point for leasing vs financing?
The break-even point is when the cumulative cost of financing equals the cumulative cost of leasing. Before that point, leasing is cheaper in total dollars spent. After it, financing becomes cheaper because you stop making payments and still hold a valuable asset. Drivers who keep their cars well beyond the loan term typically do much better financially by financing.
Does the calculator account for sales tax on leasing vs buying?
Yes — enter your state's sales tax rate and the calculator applies it to lease payments (most states tax each lease payment) and to the financed vehicle purchase price. Tax treatment differs by state: some states tax the full purchase price upfront while others tax only the monthly lease payment. The calculator uses the most common method for each scenario.
What is equity at end of term?
Equity is the estimated market value of the vehicle at the end of your loan or comparison period minus any remaining loan balance. For financing, you build equity as you pay down the loan and the car retains value. For leasing, your equity at end of term is zero — you return the car with nothing to show financially. Equity is a key advantage of financing for long-term cost comparisons.
What does cost per mile mean in this context?
Cost per mile divides the total cost of each option (payments, fees, taxes, minus equity for financing) by the total miles you plan to drive over the comparison period. It lets you compare options on a per-mile basis regardless of term length. Leasing tends to have a higher cost per mile for drivers who keep vehicles long-term because you never recoup value through ownership.
